"...to really make search work well search engines need metadata and metadata that's added by the system keeping track of your usage of files, as well as letting application developers add metadata into the system itself. In a lot of ways, weblogs are adding metadata to websites. When a weblog like mine links to a web site, we usually add some more details about that site. We might say it's a "cool site" for instance. Well, Google puts those words into its engine. That's metadata."

"Developers distrust Microsoft's intentions here. They also don't want to open up their own applications to their competitors. If you were a developer at AOL, for instance, do you see opening up your contact system with, say, Yahoo or Google or Microsoft? That's scary stuff for all of us.

But, if the industry works together on common WinFS schemas (not just for contacts either, but other types of data too), we'll come away with some really great new capabilities. It really will take getting developers excited about WinFS's promise and getting them to lose their fears about opening up their data types. "
